    Toshimori Honjo
    NTT Basic Research Laboratories, NTT Corporation, Atsugi shi 243 0198, Japan
    Opt Lett 31:522-4. 2006
    ..Extending the degree of freedom makes it possible to strengthen the DPS-QKD scheme against intercept-and-resend attacks. The feasibility of this idea is experimentally demonstrated...
